Interesting 1970s-era facts: The exteriors for the movie were filmed in Burbank, CA at the Warner Ranch and an entire colonial Philadelphia street was created. Unfortunately, most of the sets were destroyed by fire in the mid-70s.

President Richard Nixon asked producer Jack Warner to have the song “Cool, Cool, Considerate Men” removed from the movie version as it offended his political sensibilities – and it was. Many years later it was restored. Thankfully, the editor did not destroy the negative as he was asked to do.
